1 THE SECOND INDUSTRIAL AGE 1.Breakthroughs in steel processing led to a boom in railroad construction. 2. Advances in the use of oil and electricity improved communications and transportation. 3. A rush of inventions changed Americans lives.

2 BREAKTHROUGHS IN STEEL PROCESSING Americas Second Industrial Revolution started in the late 1800s. The new Bessemer process reduced the amount of time it took to make steel. The price of steel dropped because of this innovation. This made the steel industry an important part of the revolution. Cheaper, more available steel led to more railroad building. Other changes made train travel safer and smoother for passengers. Trains helped strengthen the economy by moving people and goods to their destinations quickly and inexpensively.

3 USE OF OIL AND ELECTRICITY In the 1850s scientists figured out how to turn crude oil into kerosene. Kerosene was used for both heat and light. As a result, the demand for oil exploded. In 1859 Edwin L. Drakes Titusville, Pennsylvania, oil well started producing 20 barrels of oil a day. Oil quickly became big business in Pennsylvania. Oil was also important in Ohio and West Virginia. In addition to oil, electricity became a source of light and power. Thomas Edison was an inventor interested in uses of electricity. In 1879 Edison and his assistant created the electric lightbulb. To create a market for his product, Edison built a power plant to supply industries with electricity. George Westinghouse developed a power plant that could send electricity over long distances. Thanks to Edison and Westinghouse the use of electricity in homes and business boomed.

4 RUSH OF INVENTIONS Technology also changed the way people communicated. First, telegraphs made long-distance communication possible. Then in 1876 Alexander Graham Bell was given a patent for the telephone. By 1900 almost 1.5 million telephones were in operation. Changes in transportation also occurred. The invention of the gasoline-powered engine made automobiles possible. Henry Ford began producing the first affordable automobile in 1908. He also implemented the moving assembly line in manufacturing. The gas-powered engine allowed Wilbur and Orville Wright to invent the airplane.

5 Second Industrial Revolution a period of rapid growth in U.S. manufacturing in the late 1800s
